My first code

Hi guys. Today I'm going to tell you about my special after code, it's actually pretty easy to remember
To code a message, replace each letter with the one after, like this: A=B B=C C=D and so on
So "Hello, I am Tiffany" would look something like this.......Ifmmp, J bn Ujggboz
To decode a message, replace each coded letter with the one before
A=Z B=A C=B and so on....
Easy, huh.
This is my very first and my favorite code, and if you want to check out my other blog, The One and Only Tiffany, click on the link, or go to www.slendermaniac.blogspot.com. Peace out.
